Running Your Own Cluster Is Now Simpler Than Believing in PaaS

说明与用途

使用 AI 助手自行部署集群比 PaaS 更简单、更经济，因近期停机和云成本上升。

问题

Teams rely on PaaS to avoid ops, but outages, cost, and vendor lock‑in undermine the promised simplicity, reliability, and savings.

结果

Self‑hosting with AI assistance can match or beat PaaS in cost, reliability, and control, while freeing teams from vendor‑specific ops burdens.

工作流

• 1. Assess FinOps and ops staff count
• 2. Identify fixes possible during vendor outages
• 3. Price equivalent stack on plain VMs
• 4. Verify backup ownership and location
• 5. Review recent vendor outage reports
• 6. Deploy a throwaway cluster with an AI agent over a weekend
• 7. Retain managed services only for compliance, on‑call, or burst traffic
